Hey guys,

I'm trying to passthrough the whole USB/Thunderbolt Controller to a VM to use eGPU and other Type-C Dock.. I don't want to passthrough the eGPU as it is AMD and I want to avoid GPU Reset Issues.. Also I want to be able to boot the VM, when the eGPU is not connected..

I already passed the 0000:c7:00.5 & 0000:c7:00.6 and the USB4 Controller shows up in the VM (Windows 10)..

But what about:

05:00.0 PCI bridge [0604]: Intel Corporation JHL6340 Thunderbolt 3 Bridge (C step) [Alpine Ridge 2C 2016] [8086:15da] (rev 02)
06:01.0 PCI bridge [0604]: Intel Corporation JHL6340 Thunderbolt 3 Bridge (C step) [Alpine Ridge 2C 2016] [8086:15da] (rev 02)

I cannot see them in the list when adding a PCI Device to the VM?

If I connect the eGPU it shows up on the Proxmox Host..
 
Hi glockmane,

Did you ever manage to resolve this issue? I'm stuck on the passthrough of a Thunderbolt5 egpu dock to and AMD based system too.

Hi Derek,

I solved it with installing and authorizing Thunderbold on Proxmox and then passing through the gpu to the vm (not the thunderbolt controller).
 
How did you get thunderolt to authorize, whatever 'bolt' command I use, returns nothing, and I never get the device file /sys/bus/thunderbolt/devices populated.

Can you post you modules and blacklists.?

Did you do it like that?

apt install boltctl
apt install polkitd
apt install pkexec
boltctl list -a
boltctl enroll <UUID>
lspci -nn | grep -e 'NVIDIA'

I have those installed, but as I said, the bolt command fails to detect my thunderbolt dock or the graphics card installed.
The same dock works on a Windows laptop with thunderbolt 4 and if I use the Oculink port for a PCI connection. It's all very strange.

I'll check for the modules and blacklist later..
